VFD vs Servo Drive: Key Differences
A side-by-side comparison of VFD and servo drive motor type, feedback, dynamic response, overload rating, cost, and applications for industrial engineers.
The Schneider Electric BCH18MD02332A5C is a 200 W Easy Lexium 18 BCH18 servo motor rated 0.64 N·m continuous stall torque at 1.6 A continuous stall current, built on the same 60 mm flange as the 100 W frame but with a larger medium-inertia rotor (0.268 kg.cm²). No holding brake is fitted, and the 23-bit incremental encoder needs a homing move after each power-up.
Stepping up to 200 W on the same 60 mm flange as the 100 W frame, the BCH18MD02332A5C nearly doubles continuous stall torque to 0.64 N·m while keeping the same mounting footprint, which simplifies retrofits onto an existing 60 mm-flange axis. No brake is fitted, so pick the braked BCH18MD02332F5C instead for a vertical or load-holding axis. Continuous stall current is 1.6 A; size the Lexium 18 (LXM18) drive channel to that figure rather than the 5.9 A maximum permanent current, which only covers short acceleration spikes. The 23-bit incremental encoder is the standard, lower-cost choice when the machine already runs a startup homing routine. Maximum mechanical speed is rated to 6000 rpm against the 3000 rpm nominal speed used for the torque and current figures above, leaving margin for brief overspeed during deceleration. IP67 sealing and the shared two-connector power/feedback interface mean this 200 W motor drops into the same cabling and enclosure design as the 100 W frame on the same 60 mm flange.
